Ok, this is a patch as you all know (by reading the title) about HgSs music. But it's on 3rd gen! Like ipatix' DPPt soundfont for Emerald. This is for HgSs music, and it is available for only FireRed and Emerald.

This project is old as mold. The thing is, it was never scrapped! It went from a small thing to a huge port. I would upload videos about it, but videos = work and yeah. :D Currently it is in a state where it was man-handled, meaning sappy did all of the work. Import sample assemble song yadda yadda. It took weeks at a time for small things to get done.
But now, that has all changed.
Ipatix has found a way to mass assemble the songtable, songs, voicegroups, samples and everything else using batch files. By doing this, it's an automated import in one click. So everything that would take years to do, is now done in seconds. It wastes no space since it's all thrown in safely, and there's no room for error. So by using this, your music will be flawless. Also, with Version 5, all music is re-mastered, meaning it is redone to sound like DS, no GBA, giving you better quality. Ipatix' music mixer is NOT used in version 5, as it caused issues. Please note that all of this that was said applies to the FireRed patch, not the Emerald.
If you feel like recording these songs and uploading the MP3s, please contact me for more info.

So about that information, I'm going to have videos and songs linked in the ↓down there↓

To play in Sappy without any issues do the following: Sappy Mod 15 - 17.1 -> Options -> Settings -> Extra -> DirectSound Voices Limit = 12For the FireRed version of the patch, go into sappy.xml and change the songtable offset for BPRE to 1000000.
